Product FAQs
7 answersWhat does the 1021 suffix mean on the QOB130VH1021 breaker?
The 1021 suffix indicates a factory-installed 120/240VAC shunt trip. This accessory allows the breaker to be opened remotely via an external control signal.
How many panel spaces does the QOB130VH1021 require?
Although it is a 1-pole breaker, the factory-installed shunt trip requires an additional pole space. It will occupy a total of two spaces in your panelboard.
Which panelboards are compatible with the QOB130VH1021?
This bolt-on circuit breaker is designed specifically for Square D NQ and NQOD panelboards. It cannot be used in standard QO load centers, which require plug-on mounting.
What does the VH designation mean in the QOB130VH1021 catalog number?
The VH indicates a high-interrupting capacity. While standard QOB breakers are rated for 10kAIC, this VH model provides a 22kAIC interrupting rating at 120/240VAC to safely clear higher fault currents.
What is the operating voltage for the factory-installed shunt trip?
The shunt trip coil on the QOB130VH1021 operates on a 120/240VAC control voltage.
Does this breaker include a Visi-Trip indicator?
Yes, it features the standard Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or a remote shunt trip signal, a red flag appears in the window for quick identification.
What wire sizes are accepted by the terminals on this breaker?
The pressure plate terminals are designed to accept 14 AWG to 8 AWG aluminum or copper conductors.
